Friction Inserts for automotive: solve slipping joints by increasing friction

When a bolted joint fails in simulation or testing, engineers urgently need to understand how to increase friction quickly and effectively. In automotive applications, achieving a high friction coefficient is critical to prevent slipping and ensure safety. 

Whether you are solving an urgent issue or evaluating innovation, Freudenberg Friction Inserts secure critical joints and enable higher load transmission without redesign, making them ideal for both troubleshooting and advanced engineering.

Freudenberg Friction Inserts provide a fast, production-ready alternative to traditional friction shims, enabling engineers to immediately increase friction in bolted joints.

What are Friction Inserts?

Friction Inserts are ultra-thin friction materials consisting of a nonwoven carrier coated with hard particles (industrial diamonds). These particles penetrate mating surfaces, creating a mechanical interlock that significantly increases friction.
Friction Inserts are custom made to the shape and size for every particular application.

Unlike traditional friction shims, Friction Inserts:

  • Do not affect tolerances
  • Provide consistent friction values
  • Can be integrated easily into existing assemblies
  • Do not corrode

Detailed automotive use cases

In chassis and powertrain systems, joints are exposed to increasing loads due to electrification, lightweighting, and performance demands. Typical applications include:

  • Steering systems to axle beams
  • Engine mounts and subframes
  • Gearbox housings and brackets
  • Differential connections

Friction Inserts allow project leads to quickly resolve failures without changing geometry. At the same time, predevelopment engineers can integrate them early to unlock new design possibilities. Freudenberg supports automotive teams with:

  • Fast response and sampling
  • Proven industrial scalability
  • Expertise in validation and production integration
  • Collaboration across engineering, quality, and purchasing
  • APQP logic and IATF 16949 Certified

Why Friction Increase Matters in Automotive

Increasing friction prevents:

  • Joint slippage
  • Bolt loosening or deformation
  • Noise and vibration issues

This improves safety and durability while enabling downsizing and cost efficiency.
